CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application is a continuation of U.S. application Ser. No. 12/576,391, filed Oct. 9, 2009, now U.S. Pat. No. 8,863,223, and claims the benefit of U.S. Provisional Patent Application No. 61/142,190, filed on Dec. 31, 2008. The disclosures of both of these applications are incorporated herein by reference.

BACKGROUND

[0002] 1. Field of the Invention

[0003] The invention described herein relates to a mobile set top box for receiving content and reformatting for and sending to a display the content for viewing.

[0004] 2. Background of the Prior Art

[0005] Television and internet users access content available over cable, satellite and Internet networks. Each of those networks transmits content over the networks and allows the users to view the content on a television or computer screens.

[0006] With respect to televisions, television users commonly access content using a set top box. The box is a dedicated computing device that serves as an interface between a display and a broadband network. A common set top box is a cable or satellite set top box found in homes with a cable or satellite television connection. The set top box receives a television signal over the cable lines or from a satellite dish, reformats the data in the signal and sends to a television the data for display by the television. The set top box also allows a television viewer to access content such as on-screen programming guides, interactive content such as home or auto advertisements, games or on-demand movies.

[0007] Set top boxes, however, have limitations. For example, set top boxes can be used only with the network that provides the boxes. For example, a set top box provided by Verizon FIOS can not be used on a Comcast cable network. Moreover, content output from set top boxes can only be viewed on devices which are capable of receiving TV signals.

[0008] With respect to computers, Internet users commonly access content using a desktop or laptop computer. While Internet access points are available in many locations, many computer users will not transport their desktop computers between locations. Laptop computer users often transport their laptops and some laptop users have a modem card that allows them to access the Internet over a wireless network such as Verizon's, Sprint's or AT&T's wireless networks. The laptop computers, however, usually only allow the users to view the content on the laptop screen or another computer peripheral.

[0009] Other mobile computing devices such as mobile telephones are available, but they also have limitations regarding content access. For example, along with wireless phone service, many wireless providers such as Verizon, Sprint and AT&T also provide the ability to access content over the Internet or content from the providers such as through Verizon's V Cast service.

[0010] Today, a mobile computer device such as a mobile phone, PDA or Smartphone is the primary device people use to connect wirelessly. Broadband data cards provided by wireless carriers are growing in use, but the numbers of such cards are a fraction of the number of mobile phones being used for voice and data communications. Although there are many reasons for this, a factor is the size of the mobile phone/PDA device.

[0011] Various prior art references have attempted to harness the abilities of known mobile phones. A specific example is International Publication Number WO 03/032504, for Methods and Systems of Wireless Communication Between a Remote Data Network and a Set-Top Box. This publication is directed to the field of wireless data transmission and reception. The invention disclosed therein particularly relates to a data transmission and reception system including systems and methods for using a wireless telephone to receive and transmit packet signals via a wireless or cellular network for display on a standard television using a set-top box.

[0012] The disclosure of this reference is directed to a location-specific implementation, replacing the distribution network for traditional set-top boxes in those locations where there is no wireline system. For example, the reference teaches that "there is a need for a system that provides Internet access to areas where landline telephone networks do not exist or are unreliable."

[0013] A further example is International Publication Number WO 08/136620 for a Method and System for Receiving Digital Broadcasting by Using Mobile Communication Terminal. The disclosure is related to "a system and method for receiving digital broadcasts by using a mobile communication terminal. More particularly, the invention relates to a system and a method for receiving digital broadcasts by connecting a digital broadcast receiving device to a mobile communication terminal so that the mobile communication terminal replaces circuits of the digital broadcast receiving device . . . ."

[0014] The disclosure of this reference indicates that its invention is limited to displaying over-the-air signals on a mobile terminal. This is accomplished by moving direct digital broadcast signals (e.g. DBS) that would normally be received by an antenna and set top box with the same technology.

[0015] Mobile computing devices have limitations not recognized in the cited references. Many mobile computing devices can not be connected to large display monitors. Furthermore, many wireless networks have low bandwidth in comparison to Internet, cable or satellite transmissions systems. Based on available bandwidth considerations and processing power of a particular mobile computing device, content transferred to a mobile computing device is typically sized to fit only the mobile computing device.

[0016] For example, the bandwidth of a mobile phone communicating over an Enhanced Data GSM Environment (EDGE) network, which is the protocol utilized by many Smartphones in the United States, is sufficient to support streaming content encoded for QVGA (Quarter Video Graphics Array) resolution, which may be the native resolution for a given Smartphone. However, this bandwidth is not nearly enough for supporting video at, for example, 1080p resolution (full HD), which may be the native resolution for a target display.

[0017] It can be appreciated that streaming low-resolution video from a cellular phone to an HD-TV has not been a reasonable option. However, as mobile phones approach global ubiquity, and as 3G and 4G networks as well as WiFi and WiMax begin to proliferate, the availability of high-speed wireless data transmission networks anywhere is near.

[0018] Accordingly, there is a need for a mobile set top box that combines the functionality of a set top box and a mobile communication system such that content normally available at discrete locations can be available any time, any where a user seeks access to such content.

[0019] In addition, there is a further need to enable the mobile set top box to up-convert content intended for a mobile computer device, such as a mobile phone, so that the content is properly viewed on a larger display, such as a large screen HD-TV.

SUMMARY OF THE INVENTION

[0020] The present inventions solve the aforementioned problems by providing a mobile set top box that acts as a conduit between disparate data networks and display devices.

[0021] An object of the invention is to provide a mobile set top box for gaining access to mobile content through broadband networks as well as standard over-the-air distribution.

[0022] Another object of the invention is to provide a mobile set top box that leverages the versatility of the widely accepted mobile phone/PDAs and, when combined with the mobile phones/PDAs, is used as an integrator for projection of content and interaction.

DESCRIPTION OF THE EMBODIMENTS

[0034] FIG. 1 depicts a concept used in the present inventions. A mobile set top box 10 serves as an intermediate device between disparate transmission networks 12 and disparate display devices 14. Using the mobile set top box 10, users will access content from content providers over the transmission networks 12 and then use the mobile set top box 10 to display on disparate displays 14 the content.

[0035] The mobile set top box 10 can have access to one or various communication networks, and can be capable of processing protocols provided over such networks, such as the networks and protocols listed in Appendix A, attached hereto. For example, properly configured, a mobile communication device can have access to data distributed via systems implementing ATSC technologies, IP technologies, satellite technologies and/or WiFi technologies.

[0036] In addition, unlike traditional set top boxes, the present inventions can reformat content to fit any display. The mobile set top box 10 is capable of determining the size format of the content received by the mobile set top box 10, the size format capable of being displayed by the display device 14, and performing proper up- or down-conversions for properly displaying the content on the display device 14.

[0037] That is, the mobile set top box 10 processes data meant for any size mobile computing device 10, such as a mobile phone with a three inch screen, i.e., the native resolution for the computing device 10, such that the content is capable of being properly viewed on any visual display, i.e., the native resolution for the display device 14, such as a large screen HD-TV, a computer monitor or a projector.

[0038] In other words, the mobile set top box 10 is capable of navigating the full matrix of all forms of transmission signals, all for ms of protocols provided by the transmissions (many of which are listed in Appendix A) and all forms of display types.

[0039] Moreover, up-scaling video from a mobile phone can be accomplished utilizing, for example, the "single frame super resolution LSI `.mu.PD9245GJ` chip", available from NEC Corporation, which is capable of up-scaling image data from, e.g., QVGA resolution, typically found on a mobile phone, to SXGA (Super eXtended Graphics Array) and large screen HD (High Definition Television) resolutions.

[0040] While the descriptions above and below illustrate the present inventions in connection with a mobile phone, one of skill in the art will understand the present inventions can be applied in other scenarios. For example, one of skill in the art will understand the present inventions can be applied to other mobile computing devices such as laptop computers or GPS devices.

[0041] FIG. 2 illustrates an implementation of the present inventions. The mobile set top box 10 is illustrated as a mobile phone 20 and a docking station 22. As illustrated, the cellular phone 20 merely passes information to the docking station 22 and is controlled by the docking station 22. However, the functionality of the mobile set top box 10 can be in either device. In addition, the mobile phone 20 and docking station 22 can be combined into one device. Furthermore, the display 14 is illustrated as a standard television.

[0042] As illustrated, media signals 12 from the user's cellular provider are sent to the user's mobile phone 20 and thereafter communicated to the docking station 22. The protocols which are provided over typical networks and which the mobile phone 20 is capable of receiving include, for example MediaFLO (Forward Link Only), DVB-H (Digital Video Broadcasting--Handheld), DVB-SH (Digital Video Broadcasting--Satellite services to Handhelds), and HSPA (High Speed Packet Access). Furthermore, the mobile phone 20 is capable of communicating over various networks, such as 3G, satellite, etc. Other applicable protocols and communication networks are listed in Appendix A, attached hereto.

[0043] Furthermore, converting 3GP, the multimedia container format defined by the Third Generation Partnership Project (3GPP) for 3G UMTS (Universal Mobile Telecommunications System) multimedia services to other video formats, such as MPEG-4, and/or between any of the formats listed in Appendix A, can be performed in the mobile set top box 10 through the use of readily available software and/or hardware encoders.

[0044] FIG. 2 depicts a sample protocol stack 24 that can be received and processed by a video card 26 within the docking station 22. The stack 24 includes MPEG Video 28, 30 RTP (Real-time Transport Protocol) packets, UDP (User Datagram Protocol) packets 32, IP (Internet Protocol) packets 34, DVB-H data 36. Other layers of a typical protocol stack, while not expressly listed, are implicit therein. The IP packets can be transmitted via multicast type broadcasts, and/or unicasts such as "On Demand Video".

[0045] On the output side of the docking station 22, video can be transmitted to the TV in various formats, such as DVI (Digital Visual Interface), HDMI (High-Definition Multimedia Interface), DisplayPort, S-Video (Separated Video). As indicated, the docking station 22 performs proper up-conversions of the content before transmitting the content to the TV so that the content is properly viewed on the TV regardless of how it was received by the docking station 22.

[0046] FIG. 3 illustrates another embodiment of the present inventions. There are various sources of existing content 38 which provide feeds for TV programming, live events, movie downloads, video sharing websites such as Youtube. The content is transmitted to the mobile phone 20 via the various telecommunication networks illustrated in FIG. 2 and discussed above.

[0047] The mobile phone 20 and television 14 are connected via the docking station 22 as illustrated in FIG. 2 and discussed above. The docking station 22 determines the video display characteristics capable of being provided by the phone 20, i.e., its native resolution, and type of video display characteristics capable of being displayed by the television 14, i.e., its native resolution, which can be far greater than the native resolution for the phone 20. Upon receiving content from the networks, the mobile phone 20 transfers the information to the docking station 22, which up-scales the content and displays the content on the television 14.

[0048] FIG. 4 illustrates another embodiment of the present inventions. The system 12 can include a content manager 42 which receives all information from the various content sources 38 and organizes the information for downstream viewing on the television 14 by the user. That is, the content manager 42 organizes content distributed over the various networks 40 and provides, for example, a program guide, remote control functionality, and, if needed, content filtering.

[0049] In use, a standard mobile phone supporting the relevant mobile networks will have a display to allow the user to navigate available content and select content. When the phone attaches to the disclosed docking station it thereafter may be connected to any of a number of devices.

[0050] At that point, the phone or docking station will accept external power enabling it to support a second, more capable processor and video controller. The docking station will take the output of the phone and allow it to connect to a television, data terminal or other external device. In the embodiment in which the handset and docking station are integrated, no such connection is necessary.

[0051] The mobile phone can connect to the docking station through a wired or wireless connection. Likewise, the disclosed docking station can connect to an external display system both wired and wirelessly. As previously indicated, in the embodiment in which the handset and docking station are integrated, no such connection is necessary.

[0052] Accordingly, the disclosed mobile set top box meets the objects of the invention by being capable of: [0053] a. gaining access to mobile content through broadband networks; [0054] b. leveraging the versatility of the widely accepted mobile phone/PDAs which, when combined with the mobile phone/PDAs, is used as an integrator for projection of content and interaction; [0055] c. authenticating a user so that the user can receive media service; [0056] d. receiving programming information via a cellular or other network, receiving a selection of real time or stored video and audio from a user, and performing up-scaling for displaying the media configured for a mobile computing device, such as a cellular phone, on a large screen HD-TV. [0057] e. serving as an intermediate component for receiving video and audio from cellular or other networks; [0058] f. enabling a user to "surf channels"; and [0059] g. processing video-on-demand (VOD), Electronic Program Guide (EPG), digital rights management (DRM), and a variety of interactive and multimedia services.

[0060] In sum, the disclosed mobile set top box acts as a conduit between disparate data networks and media devices--televisions, interactive terminals, etc., extending internet access and video content to those devices.

[0061] The purpose of the foregoing description of the is to provide illustrations of the inventions described herein. The foregoing description is not intended to be exhaustive or to limit the inventions to the precise forms disclosed. One of skill in the art will obviously understand many modifications and variations are possible in light of the above principles. The foregoing description explains those principles and examples of their practical application.
